 [Osiris Right]
 
"The stars in the celestial heights are obedient unto thee, and the great doors of the sky open themselves before thee. Thou art he to whom praises are ascribed in the southern heaven, and thanks are given for thee in the northern heaven. The imperishable stars are under thy supervision, and the stars which never set are thy thrones."

Hymn to Osiris from The Egyptian Book of the Dead
(The Papyrus of Ani, 1240BC), tr. E. A. Wallis Budge (1895).

  

Abstract

The Ohio State Infrared Imager/Spectrometer (OSIRIS) is a multi-purpose infrared imager and spectrometer. The instrument is used at the f/16 focus of the SOAR 4.1m telescope at 1-2.5 micron wavelengths. The instrument currently uses a 1024x1024 HgCdTe array supplied by CTIO. Internal optics allow for two plate scales and a variety of spectroscopic resolutions. Internal mechanisms control the selected filter, focal plane mask, pupil mask alignment, grating tilt, and optical arrangement. All mechanisms are user controlled and can be used to rapidly reconfigure the instrument, which allows for substantial observing flexibility.
